SEM: OWL issues affecting OWL semantics

I have been doing a bit of thinking about OWL semantics and have identified
a number of issues that affect semantics.  I have categorized these issues
with respect to my view of how they affect work on OWL semantics.  Some
issues have just been raised (by me).

Comments are requested.  In particular, does anyone know of other issues,
including issues just raised (by you), that directly affect work on the
semantics of OWL?

		Semantic Issues to be Resolved


Issues that MUST be resolved for semantic work to proceed:

Issue 5.3: Semantic Layering

	Without a resolution of the semantic layering issue, no work on
	semantics is possible.

Issue ?: DAML+OIL semantics is too weak

	This issue is related to the semantic layering issue, and is vital
	to the OWL semantics.

Issues that MUST be resolved for semantic work to complete:

Issue ?: Datatypes

	OWL semantics will have to include a treatment of datatypes.  RDF
	Core is apparently not producing a treatment of datatypes and
	DAML+OIL datatypes have problems.

Issues that SHOULD be resolved for semantic work to complete:

Issue ?: Malformed DAML+OIL Restrictions

	It would be useful to be able to exclude malformed DAML+OIL
	restrictions, particularly restrictions with extra components.
